I have heard (or read) about painters who sometimes turn the canvas upside down to check the composition as the act of rotating it reduces the image to shapes instead of instantly recognisable objects.
View camera users have that facility built in!

This is why I get such good composition on my Brownie No.2 Cameras. The viewfinders on those are tiny groundglass waistlevel viewfinder things about 8mm x 15mm. You definitely see the overall picture a lot better than any details.
